The Panasonic Viera is a line of HDTV sets available in a variety of screen sizes, including LED and LCD display formats. All Viera models are equipped with a digital audio output jack that lets you connect the HDTV to external audio devices such as a sound bar, which is a multi-speaker component that mounts above or below a TV set. Sound bars are available from several manufacturers with different features. If your sound bar has a digital optical input, you can connect it to a Panasonic Viera.
Press the "On/Off" button on the Viera remote to shut off the HDTV before connecting the sound bar.
Plug in one end of the digital audio optical cable into the matching digital audio optical output port on the rear panel of the Viera.
Connect the other end of the cable to the input port on the back of your sound bar.
Plug in the power cord for the sound bar and turn on the Viera HDTV.
